Blood gets its color from the presence of oxegenated iron.
The greenish color of bile is primarily due to the presence of bilirubin, which is a breakdown product of hemoglobin from red blood cells. When red blood cells are broken down, hemoglobin is converted into biliverdin, which then gets further converted into bilirubin. The bilirubin is then processed by the liver and excreted into bile, contributing to its characteristic color.
due to the presence of haemoglobin
Blood is always red.
Oxygenated blood is red. The presence of carbon dioxide in the blood does not alter the color.
The blood of a lizard is typically red, just like the blood of other vertebrates. The red color comes from the presence of hemoglobin, a protein that carries oxygen in the blood.
The guaiac reagent turns blue when oxidized in the presence of blood. This color change occurs due to the reaction of guaiaconic acid with the heme component of hemoglobin in blood, catalyzed by peroxidase activity. This property makes the guaiac test useful for detecting the presence of blood in various samples.
Hematuria
Blood appears red due to the presence of red blood cells, which contain a protein called hemoglobin that binds to oxygen and gives blood its red color. The yellow color of plasma is due to the presence of proteins and fats in the liquid component of blood. When combined with the red blood cells, the overall color of blood appears red.
The villi in the small intestine are typically a pinkish color due to the presence of blood vessels.
Your blood type is determined by the presence or absence of certain antigens (proteins) on the surface of your red blood cells. The ABO system determines your blood type based on the presence of A and B antigens, while the Rh system determines the positive or negative factor based on the presence of the Rh factor (or antigen D). These antigens are inherited from your parents through their genes.
No it stays blue, it only turns blue in the presence of blood
Urine has a yellow color due to the presence of urobilin, a product of the breakdown of red blood cells. The intensity of the yellow color can also be affected by hydration levels and the concentration of waste products in the urine.
